Nikkiso canned motor pumps HX Series are centrifugal pumps which are hermetically encapsulated. The shaft seal usually installed for centrifugal pumps is not required. The pumps are driven by integrated canned motors especially designed for high temperature applications. Space requirement and noise emission are much lower than those of conventional centrifugal pumps. The pumps are equipped with Nikkiso's unique bearing monitor.
